SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 438,006, dated October 7, 1890.

Application filed April 12, 1890. Serial No. 341664 (No model.)

To aZZ whom it may concern:

Be it known that we, BENJAMIN E. LECKRON, aresident of Glenford, Perry county, Ohio, and ALFRED CASTANIEN, a resident of Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Spring Bed-Bottoms; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention has relation to spring bedbottoms, and particularly to that class employing spring mattresses or webs. Heretofore in this class of devices it has been found diificult to provide a construction whereby the sagginglincident thereto could be readily taken up and compensated for.

It is the primary object of our invention to accomplish this desirable end in a simple and expeditious manner, and it is a further object to provide a construction whereby a most comfortable and readily-yielding bed is produced.

With these objects in view our invention consists in the improved construction and combination of parts, as hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings,Figure 1 is a perspective view of our improved spring bed-bottom. Fig. 2 is a section of one end, showing the manner of retaining the tensionroller in its adjusted position and Fig. 3 is a cross-sectional view taken through the ten sion-roller on line a; :20, Fig. 2.

Like letters of reference indicate like parts throughout the several views of the drawings.

Referring to the drawings, the letters A A represent the side pieces of the frame, said side pieces being provided with concaved ends a a. Extending out from these concaved ends of the side pieces are iron bands B B, their outer portions being rounded so as to conform to the concaved ends of the side pieces, thus forming circular bearings. The inner ends of these bands are secured to the side pieces by means of bolts 0 or equivalents. At one end of the frame is journaled in the bearings above described a roller D, while at the opposite end of the frame is journaled a similar roller E.

The letter F indicates a wire mattress or web, which passes around the roller D, and the ends of the upper and lower portions thereof are connected to roller E, preferably by means 5 5 of staples G, driven therethrough and into said roller. lVe have also shown in the drawings as an additional securing means the transverse rod or wire H, which passes through the staples above the secured ends of the 6(- wire mattress. It is obvious, however, that any other suitable means may-be employed for connecting the ends of the web to the roller without departing from the spirit of our invention. Interposed between the upper andlower portions of the wire mattress are the usual transverse slats I, to which are secured helical springs J, the upper ends of said springs bearing against the upper portion of the wire mattress, while the transverse slats 7c are supported by the under portion of said wire mattress. The springs J may be secured to the slats I by inserting their lower ends in apertures in said slats or in any other manner found convenient or desirable.

It will be seen from the drawings that one end of the roller E has mounted fast thereon a ratchet-wheel K, which is adapted to be engaged by a spring-actuated pawl L, pivoted to the corresponding side piece of the frame. 8o Any other suitable spring-catch may, however, be employed, if preferred.

From the foregoing description the construction of our improved spring bed-bottom will be readily understood.

In operation, when any sagging or uneven ness of the wire mattress is observed all that is necessary to be done is simply to turn the tension-roller E in the direction indicated by the arrow in Fig. 1, and when turned in the desired position the pawl L will fall into engagement with the ratchet-wheel and prevent the roller from returning to its former position. When the roller is rotated as just described, it will have the effect of carrying the 5 attached ends of the wire mattress outwardly, thus tightening said mattress and compensating for any sagging or looseness. The roller D upon the opposite end of course facilitates the movement of the mattress.

From the foregoing description the operation, construction, and advantages of our improved spring bed-bottom will be readily understood.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is-

1. Ina spring bed-bottom, the combination of side pieces having concaved or grooved ends, bands or straps secured to the ends of the side pieces and forming in connection therewith circular bearings, a roller journaled in one end of the frame, a tension-roller journaled at the opposite end, means for retaining the latter roller in an adjusted position, a wire mattress or Web having its ends secured to the tension roller and passing around the opposite roller, and transverse slats providedwith helical-springs interposed between the upper and lower portions of the wire mattress substantially as set forth.

2. In a springbed-bottom, the combination of side pieces provided with end bearings, a roller journaled in one end of the frame, a tension-roller journaled'in the opposite end, a Wiremattress or Web passing around one of the rollers, staples for securing the ends of the mattress to the tension-roller,a transverse rodlpassing through said staples, means for retaining the tension-roller in its adjusted position, and transverse slats provided with helical springs interposed between the upper 30 and lower portions of the wire mattress, substantially as set forth.

3. In a spring bed-bottom, the combination of side pieces having concaved or grooved ends, bands or straps secured to the ends of 5 the side pieces and forming in connection therewith circular bearings, a roller journaled in one end of the frame, a tension-roller journaled in the opposite end, said roller having one end extended and rigidly mounted o thereon a ratchet-wheel, a spring-pawl pivoted to the side piece and adapted to engage the ratchet-wheel, a wire mattress passing around one of the rollers, staples for securing the ends of the mattress to the tension-roller, 5
